A block `A` of mass `m_(1)` rests on a horizontal table. A light string connected to it passes over a frictionless pulley at the edge of table and from its other end another block `B` of mass `m_(2)` is suspended. The coefficient of knetic friction between the block and table is `mu_(k)` . When the block `A` is sliding on the table, the tension in the string is.

A

`((m_(2)-mu_(k)m_(1))g)/((m_(1)+m_(2))`

B

`(m_(1)m_(2)(1+mu_(k))g)/((m_(1)+m_(2)))`

C

`(m_(1)m_(2)(1-mu_(k))g)/((m_(1)+m_(2)))`

D

`((m_(2)+mu_(k)m_(1))g)/((m_(1)+m_(2)))`
